What if i relapse on coke for awhile to quit fent?

i know a lot of people have said its a terrible idea but i remember that before i did fent, i did coke and actually ii had absolutely no problem quittting that whenever i wanted to. i never really experienced any negative effects at least to the extent that fent withdrawl is. with coke i just felt nauseous around food. i wonder if i could seriously quit this shit for good by switching to coke that way im not thinking about hoe shitty i feel and how much i meed a line(ima habitual snorter) i just got my big girl job and quit serving like three weeks ago and somehow passed the drug test to even get this job (its an office job) and feeling bad by 2pm everyday wanting to leave work is just not working for me and my mind keeps going back to when i used coke i had no issues. i truly wish i never started with fent. fuck fent.
